If Jesus is the son of God, why is he described as “Everlasting Father” in Isaiah 9:6?

God is revealed as “one God in 3 persons”. Having lived in time and space my whole life, I honestly don’t know if I am even able to understand. In the beginning was the Word and the Word was with God and the Word was God, John 1:1 says. That statement alone makes no human sense, but it makes sense to God. How can you be with AND was??? I can’t understand it, but I believe it.

Check out the previous blog because the question was similar. But to get an ultra specific answer from one of our elders, check out this sermon from Rich Sprunk. It is laser focused on the very phrase in question:
